You will need:
1.- A heating tool- I've had a couple of these, and don't find there to be much of a difference, so I would recommend going by price.
2.- Embossing powder- There are many colors and powder varieties. If you are just starting out, I am going to recommend you buy the clear, fine powder. Coloriser is a good brand, and its about $4.00 a jar and will last forever.
4.- A stamp, wood stamp or a clear stamp, but not a digi stamp. Don't worry this technique is not going to ruin your stamps. I like to get most of my stamps from Sherri Baldy they are always sweet and make me smile. You can find them here at: My-Besties
Here is the image that I embossed last night....
Very easy and simple
1. Stamp your image using a pigment ink pad.
2. Quickly pour embossing powder over your image and shake it around being sure to cover the whole image.
3. Pour the excess powder back into the bottle. (I like to fold a piece of paper in half so That I don't spill, glides right back in to the bottle)
4. Use your heating gun to melt the powder onto your image. You will see it become darker when it starts to melt. Warning... (do not hold your heating gun too close to your paper or you will get brown marks)
5. Color your image if you wish.
Come give it a try, it's a lot of fun.
